Aerocel® AC Sheet & Roll


Aerocel AC Sheet & Roll has everything you would want or expect from closed-cell sheet insulation – excellent moisture resistance, low thermal conductivity, and superb noise absorption, etc. Plus, it’s made with a proprietary blend of EPDM rubber that makes it uniquely durable when exposed to moisture, water vapor, and UV.

Broadly applicable, this closed-cell elastomeric insulation is available in a wide range of thicknesses. See submittal sheet for thicknesses and corresponding R-values.

Most thicknesses are available with or without a pressure-sensitive adhesive backing for faster installation.
